Stochastic MINLP optimization using simplicial approximation

Mathematical programming has long been recognized as a promising direction to the efficient solution of design, synthesis and operation problems hat can gain industry the competitive advantage required to survive in today’s difficult economic environment. Most of the engineering design roblems can be modelled as MINLP problems with stochastic parameters. In this paper a decomposition algorithm is presented to solve convex tochastic MINLP problems. The proposed approach is an extension of the simplicial approximation approach proposed by Goyal and Ierapetritou Goyal, V., & Ierapetritou, M. G. (2004a).

Computers and Chemical Engineering, 28, 1771], for solving eterministic MINLP problems and is based on the idea of representing the feasible region by a close approximation of its convex hull. Two case tudies are presented illustrating the applicability and efficiency of the proposed approach. 2006 Elsevier Ltd. All rights reserved.
